Rejected Email Format

[PetrolTed]

Does anyone know if there are standards for the format of rejection messages from email providers?

I need to parse rejection messages that I receive in response to my outgoing mail lists in a more efficient manner than I'm doing currently. I'd like to know if there are some defined formats for the mails that I will be parsing.

Ted,
The format of the mail that comes back to your e-mail account can vary in format and wording, as it is dependant on the mail server/mta that generates it.
If it's actual SMTP session debug you want to parse, then basically a 2xx code is "OK", 4xx code is a temporary failure, 5xx code is a permanent failure.
Cheers,
